Kawasaki Z900RS

"but that extra 25 HP and 80-pound weight difference"

more like 15 hp (stock CB dynos about 85 rwhp the new RS will dyno about 99 rwhp... the full bore Z900 only dynos 113 rwhp or 28 hp more than the CB)

the weight difference is 70 pounds (CB 545 lbs... RS 475 lbs)

Honda says 540 on its website. Honda shows no difference between the weights of the Standard and Deluxe models which is likely an error since the Deluxe holds more fuel and has twin exhausts. The EX has even beefier suspension and holds even more fuel than the Deluxe, another half-gallon. None of that weight seems to be taken into account, so I think Honda have not updated the specs correctly, since two reviewers using independent scales are coming up with 562 and 570 lbs, respectively.

Horsepower, yes, I gave a rough number, I am speaking of crankshaft horsepower claimed, not dyno numbers. Dynos vary from day to day and bike to bike so I don't put much stock in those values. The use of a dyno is mainly to chart changes and make sure the bike is running properly, those numbers are all over the place.

Dyno threads are worse than oil threads on the high-performance bike websites...

So, Honda are claiming 88 HP or 89 PS for the EX, Kawasaki are claiming 110 HP or 111 PS for the RS model. So, the difference is 22 HP at the crank. The buyer considering either will surely take these values into account and figure out what they mean for him or her. But the "motojournalist" on the CB1100EX who is getting left well behind is bound to comment on the performance gap.

If that's important, the choice is more obvious. If not, the CB1100 might be a contender.

If I didn't already own a Z900R I'd be a prime candidate for the RS but that not being the case, another CB1100 (EX this time) might be in the cards.
